Coffee is one of the most consumed beverages globally, with millions of people relying on it for their daily dose of energy and flavor. Whether you prefer your coffee black, with milk, or sugared, the quality of the coffee powder is crucial for a perfect cup. However, have you ever wondered if coffee powder can spoil? The answer to this question is more complex than a simple yes or no, as it depends on various factors including the type of coffee, storage conditions, and handling practices. In this article, we will delve into the world of coffee powder, exploring its shelf life, storage requirements, and signs of spoilage.
Introduction to Coffee Powder
Coffee powder, also known as instant coffee or ground coffee, is made by drying and grinding coffee beans into a fine powder.
